Story summary

A team from The University of Texas at Austin found early Martian volcanoes released reactive sulfur gases, potentially enabling life.
Researchers analyzed Martian meteorites and ran over 40 simulations to explore ancient Mars's chemistry.
They found eruptions released reduced sulfur species such as hydrogen sulfide and sulfur hexafluoride, potentially driving a greenhouse effect.
The findings align with NASA's discovery of elemental sulfur on Mars, supporting substantial sulfur cycling.
